3 Setup Set shop air pressure regulator (not supplied) according to paint manufacturer s recommendation. See maximum air and fluid pressures on cover. Make sure no air restrictions, such as low-volume cheatervalves, obstruct the air flow. If an air adjusting valve is desired, use a SHARPE Air Adjusting Valve 24AAV (part no. 220), 36AAV-HOV (part no. 330) or HOV (part no. U0440). Install a shutoff valve (not supplied) downstream of the air regulator to shut off gun air. Install an inline air filter (not supplied) to clean and dry the air supply to the gun.. Turn off air and fluid supply. 2. Connect a clean, dry, filtered air supply to gun air inlet (2). 3. Connect fluid supply line to gun fluid inlet (A). 4. If this is first time using the equipment, flush the spray gun. Flushing Read warnings, page 2. Flush before using the equipment, before changing colors, and when you are done spraying. Use solvent that is compatible with gun wetted parts and fluid that will be sprayed. Flush at lowest possible pressure. Refer to Compliant Cleaning Methods, page 4, to comply with air quality laws if applicable.. Follow Pressure Relief Procedure. 2. Connect solvent supply to gun fluid inlet. 3. Spray into grounded metal waste container until equipment is clean. 4. Follow Pressure Relief Procedure. 7 Spraying CAUTION Excessive atomizing air pressure can increase over-spray, reduce transfer efficiency, result in a poor quality finish from dry spray. Regulatory agencies in certain states prohibit the operation of a spray gun above 0 psi (69 kpa,.7 bar) atomizing air cap pressure. FIG. A 2. Slowly adjust gun air pressure while fully triggering the gun until you have the desired atomization. 2. Adjust the pattern size and shape with the spray width adjustment knob (). Turn knob clockwise to reduce pattern size and counterclockwise to increase it. Operation Pressure Relief Procedure See Troubleshooting guide if you experience an irregular pattern. 3. Fluid control knob (7) is factory set for maximum needle trigger travel and material flow. To decrease needle/trigger travel and decrease fluid flow, turn knob clockwise. Follow Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing equipment. Read warnings, page 2.. Turn off gun air and fluid supply. 2. Trigger the gun to relieve pressure C

4 Cleaning and Maintenance 2. Use a rag moistened in solvent to wipe outside of gun. 3. Blow dry gun inside and out. Lubricate gun as described in Spray Gun Maintenance. Cleaning Nozzle and Air Cap Follow Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing equipment. Read warnings, page 2. CAUTION Do not submerge gun in solvent. Solvent dissolves lubricant, dries out packings, and may clog air passages. Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern. Use a compatible solvent. Gun can be cleaned in a gun washer. Clean air line filters as directed by the manufacturer. Volatile Organic Compounds (VOC) Regulation In certain states, spraying solvents that release VOC s into the atmosphere when cleaning a spray gun is prohibited. To comply with these air quality laws you must use a cleaning method that prevents the escape of VOC vapors into the atmosphere. See Compliant Cleaning Methods below. Compliant Cleaning Methods Place spray gun in a gun washer that completely encloses the gun and components during cleaning, rinsing, and draining. Spray solvent through the spray gun into a closed gun cleaning station. Cleaning Gun Refer to Compliant Cleaning Methods to comply with air quality laws if applicable.. Follow Flushing procedure, page 3. CAUTION Trigger gun whenever you tighten or remove nozzle to avoid damaging needle seat and nozzle. Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern. To clean the air cap and nozzle, remove and soak them in a compatible cleaning solution. Clean them and front of gun with a soft-bristle brush dipped into compatible solvent. Do not use a wire brush or metal tools. To clean out air cap holes, use a soft implement, such as a toothpick. Spray Gun Maintenance Frequently lubricate the gun moving parts with a drop of non-silicone oil (part no. 8255). Do not disassemble the spray gun if you are having a spray pattern problem. Check Troubleshooting, page 5, for information on how to correct the problem. Check for fluid leakage. Tighten fittings or replace equipment as needed.
